Experience one of the engineering wonders of the world – the Hoover Dam. When completed in 1935, it was both the world’s largest electric power producing facility and the world’s largest concrete structure, and it is currently the world’s 34th largest hydroelectric generating station. During the tour you will be able to view the seventeen turbine-generators that produce up to 2,074 megawatts of hydroelectric power. You’ll also see the Arizona spillway and the Arizona Look Out.
